I posted this same question a few months ago. and i am now just getting around to possibly working on my car. The problem is that the tranny will not shift out of first, if it does it goes to a neutral type postition and the engine just revvs. also the spedometer stopped working the same time the tranny started what it has started.

I did a search on the governor because that is what some people said might be wrong. this was the only related link i could find... http://www.peachparts.com/shopforum/showthread.php?t=144710&highlight=Governor ...

I was wondering if the W116 trannies and the W124 (i think is the thread's vehicle) are the same procedure and if anyone knew the PN that i had to find for my car. it is a 80' 300SD. the part number for the gear and the selinoid (i think) that is on the opposite side of the governor. If i even have the selenoid.

Thanks in advance
